Abstract

The present invention provides a method and system for securing audio data. The method includes receiving audio input signals from an input port, receiving at least one noise signal from a noise source, generating encoded audio by a signal encoder encoding the audio input signals with the at least one noise signal, decoding the encoded audio by a signal decoder playing the encoded audio with an out-of-phase version of the at least one noise signal, and playing by an audio output component the decoded audio.
